摘　　要：设计了高精度分布式光纤传感测温系统，通过理论分析与数值仿真对影响系统的关键参数进行研究，针对不同定标精度选取特定参数值，将测温范围提高至30℃～160℃，测温精度提高0．02℃。The distributed optical fiber sensing temperature measuring system with high precision was de- signed and researched in the paper. The key parameters affecting the performances of system were studied both the theoretical analysis and numerical simulation, the specific parameters were selected for different cali- bration accuracy, the temperature measurement range was increased to 30℃～160℃ and its accuracy was in- creased by 0.02℃.
